Core Scientific Bets $3.3 Billion on CoreWeave, Walks Away From Bitcoin

Core Scientific is going all-in on the AI buildout, and it is willing to borrow at junk-grade rates to get there. The Austin miner said Tuesday it will offer $3.3 billion in speculative-grade senior secured notes due 2031, funneling a chunk of the proceeds into the six data center campuses it is racing to deliver for cloud-computing partner CoreWeave. The rest covers existing debt. Nothing about this is cheap. Nothing about it is cautious either.

Core Scientific Trades Hash Rate for AI Rack Space

Call it a reinvention, call it a retreat from hash rate, the direction is the same. Core Scientific confirmed the offering in a statement on Tuesday, valuing itself at roughly $6.55 billion in the process. The firm declined to disclose the coupon rate on the new notes or the exact day investors will be able to buy them. That silence is standard for a deal still being shopped, but the sheer size of the raise tells the story on its own. This is the biggest single capital move Core Scientific has made since it crawled out of Chapter 11 in 2024.

CEO Adam Sullivan framed the raise as fuel for speed. The company wants to shorten the timeline on projects already under construction, and cash is the lever. Sullivan said Core Scientific would be deploying capital to accelerate service timelines associated with its projects. Translation: the race to plug in high-density data center capacity is on, and the company that finishes first wins the contract renewals.

The CoreWeave Deal Is the Whole Thesis

Strip away the junk-bond headline and what is left is a single customer relationship carrying the entire strategy. Core Scientific is building six data center facilities under a 12-year agreement with CoreWeave that could generate roughly $10 billion in revenue over its life, according to a person with direct knowledge of the matter cited by a report on Tuesday. That one contract is why lenders are willing to look at speculative-grade paper from a company whose legacy business is Bitcoin mining.

The math is brutal and simple. Spend $3.3 billion now, lock in a decade-plus of recurring revenue, refinance whatever legacy obligations still sit on the balance sheet. The risk sits with the bondholders and, indirectly, with shareholders if CoreWeave’s own growth story hits a wall. AI infrastructure demand has been red hot across the U.S. for most of 2026, and Core Scientific shares have climbed 42% year-to-date on the thesis. On Tuesday alone the stock rose 4.5% to $20.77.

• 12-year term with CoreWeave, the longest customer commitment in Core Scientific history
• $10 billion in projected revenue over the life of the agreement
• Six high-density data center campuses under construction
• 2031 maturity on the new notes, giving roughly five years of runway past delivery

Why Is Core Scientific Selling Its Bitcoin?

Mining does not scale fast enough to fund the buildout. Core Scientific indicated it would continue offloading Bitcoin to finance the pivot. CFO Jim Nygaard estimated the company now holds fewer than 1,000 BTC after selling 1,900 Bitcoin for $175 million in January, down from 2,537 BTC at year-end 2025.

The remaining stack would be worth roughly $192 million today with BTC changing hands around $75,800. That is a remarkable unwind for a company that once branded itself as one of the largest Bitcoin miners in North America. When Core Scientific emerged from bankruptcy in 2024, its fleet had produced 13,762 BTC the previous year, a haul worth close to $1 billion at today’s prices. Now the bitcoin on the balance sheet is being treated like inventory, sold down to fund capex. The purists will call it betrayal. The shareholders will call it arithmetic.

Morgan Stanley Was Already in the Room

The $3.3 billion note sale does not arrive in a vacuum. It sits on top of the up to $1 billion in strategic financing Core Scientific secured from Morgan Stanley earlier in the pivot. Stack the two together and you have more than $4.3 billion in fresh capital earmarked for the AI conversion in a matter of months. That is real money, and it is also a real answer to anyone still asking whether Wall Street believes in the trade.

Investors bidding on the new notes will be pricing two risks at once. The first is operational, can Core Scientific actually deliver six data center campuses on time without cost overruns. The second is concentration, because CoreWeave is both the customer and the thesis. If CoreWeave stumbles, the collateral story on these notes gets a lot less comfortable. The bond market has shown it is willing to fund AI infrastructure buildouts at speculative grades, but the terms will tell the real story when the coupon lands.

Bitcoin mining has remained the firm’s biggest money-maker, yet the company is racing to distance itself from the leading digital asset.

The Awkward Truth in the Quarterly Numbers

Here is the part the pivot narrative glosses over. In the fourth quarter, Core Scientific earned $41.1 million from mining Bitcoin for its own account compared with $31.3 million from colocation. Mining, the business the company is visibly distancing itself from, is still the biggest money-maker on the income statement. Colocation, the business being sold to Wall Street as the future, is not yet dominant in the numbers.

That gap is why the balance-sheet moves matter so much. Core Scientific cannot wait for colocation revenue to organically overtake mining. The CoreWeave contract forces the timeline. Every month a data center site is not energized is a month of deferred revenue, and the $3.3 billion raise is essentially the company buying back time.

It is also the reason the BTC sales keep accelerating. Holding Bitcoin on the balance sheet is a luxury a company with this capex plan cannot afford. Every coin that goes out the door is a coin that does not have to be raised in equity or debt, and equity at this price is not something management wants to issue more of.

Core Scientific Is Not Alone, and That Might Be the Problem

The pivot-to-AI trade is crowded. Hut 8, TeraWulf, Riot Platforms, MARA Holdings, and Bitfarms are all angling for the same hyperscaler contracts, the same grid interconnections, the same construction crews. Core Scientific has a head start with the CoreWeave anchor, but margins across the cohort will compress as more miners finish their own conversions.

There is a scenario where the AI infrastructure gold rush produces a handful of winners and a long list of companies that converted just in time to watch capacity outstrip demand. There is also a scenario where hyperscaler demand keeps outrunning supply through 2028, and every former miner with a ready site gets bid up. Nobody hawking $3.3 billion of 2031 paper wants to talk about the first scenario, but bondholders will price it anyway.

• Hut 8, pivoting into high-performance compute hosting
• TeraWulf, signing AI tenants at its Lake Mariner facility
• Riot Platforms, evaluating mixed-use buildouts
• MARA Holdings, expanding energy footprint with AI optionality
• Bitfarms, revisiting power contracts for higher-density tenants

What Happens Next for Core Scientific?

The near-term checkpoints are clear. The coupon on the 2031 notes will set the first real market verdict on the pivot. Construction milestones on the six CoreWeave sites will set the second. Q1 and Q2 earnings will tell shareholders whether colocation revenue is finally closing the gap with mining, and whether the remaining Bitcoin stack has been drawn down faster than expected.

If Core Scientific hits its timeline and the CoreWeave revenue ramps on schedule, the junk-bond label becomes a footnote, something the company refinances into investment-grade paper a few years out. If costs creep or delivery slips, the 2031 maturity turns into an anchor. Either way, the company has chosen. The mining era is over in everything but the quarterly numbers, and even those are on a countdown.
